Abstract
Description
[Technical Field]
[0001] The present invention relates to a bag, and more particularly to a hand-held travel bag that can more easily carry a large amount of luggage. [Background technology]
[0002] Suitcases are useful when traveling because they can easily carry heavy luggage using casters. Some suitcases are equipped with shoulder straps so that they can be used as backpacks when using stairs or riding a bicycle.
[0003] When a suitcase with this backpack function is wheeled with the shoulder straps attached, the shoulder straps may sag and come into contact with the ground, becoming dirty, or the wheels may run over the shoulder straps.
[0004] For example, Patent Document 1 proposes providing a pocket on the outer surface of the bag body for storing the shoulder straps after removing them from the bag body when the suitcase is being wheeled. The technology disclosed in Patent Document 1 has the advantage that the shoulder straps can be stored in the pocket while the suitcase is being wheeled, preventing them from getting dirty.

[0005] [Patent Document 1] Japanese Patent Application Publication No. 8-280431 Summary of the Invention [Problem to be solved by the invention]
[0006] However, since the suitcase itself is too heavy, there are few opportunities to use the shoulder strap, and there is a demand for smaller and lighter suitcases.
[0007] The inventor has accumulated many years of research and development experience in the related field, and after many years of hard work, has thoroughly discussed the above drawbacks and actively sought solutions based on the above requirements, and finally completed this invention. [Means for solving the problem]
[0008] The present invention provides a bag having a left storage section capable of storing items inside, a right storage section connected to one side of the left storage section and having a roughly rectangular parallelepiped shape similar to the left storage section, capable of storing items inside, a left handle attached to the outside surface of the left storage section, and a right handle attached to the outside surface of the right storage section and having a shape similar to the left handle, the left and right storage sections being able to be aligned with each other using the connected side as an axis, and when aligned, the left and right storage sections can be fastened together with a zipper, and two shoulder straps, one on each side, are attached to the outside surface of either the right storage section or the left storage section. [Effects of the Invention]
[0009] The bag of this invention has the excellent advantage of being able to store a large amount of clothing and being easy to carry using the shoulder strap or handles. [Brief explanation of the drawings]
[0010] [Figure 1] 1 is a perspective view showing an example of a bag according to the present invention. [Figure 2] FIG. 2 is a front view of the bag of FIG. 1. [Figure 3] FIG. 2 is a rear view of the bag of FIG. 1. [Figure 4] FIG. 2 is a perspective view showing the inside of the bag of FIG. 1 when opened. [Figure 5] FIG. 2 is a perspective view showing the inside of the bag of FIG. 1 when opened. [Figure 6] FIG. 2 is a perspective view showing the inside of the bag of FIG. 1 when opened. DETAILED DESCRIPTION OF THE INVENTION
[0011] In order to more clearly understand the object, utility, features and structure of the present invention, preferred embodiments are illustrated and described below with reference to the drawings.
[0012] Fig. 1 is a perspective view of the bag of the present invention, Fig. 2 is a front view of Fig. 1, and Fig. 3 is a rear view of Fig. 1. The bag of the present invention can be carried by holding the left and right handles 40 as shown in Fig. 1, or by hanging it over the shoulder using the shoulder strap 30. The bag of the present invention can be carried in two different ways, making it more flexible to use than conventional bags.
[0013] 4 to 6, the handbag 100 of the present invention has a left storage compartment 10 whose interior can be opened and closed by opening and closing a zipper 50, capable of storing items therein, a right storage compartment 20 connected to one side of the left storage compartment 10 and having substantially the same shape as the left storage compartment 10, and capable of storing items therein, a left handle 40 provided on the outer surface of the left storage compartment 20, and a right handle 40 provided on the outer surface of the right storage compartment 20 and having substantially the same shape as the left handle 40. The left and right storage compartments 10 and 20 can be fastened together by a zipper at the joined portion of their outer peripheries with one side of the left storage compartment 10 and one side of the right storage compartment 20 aligned about the connected side. Furthermore, two shoulder straps 30 are attached to the outer surface of either the left storage compartment 10 or the right storage compartment 20, one on each side.
[0014] Here, the shoulder strap 30 is detachably attached to the outer surface of either the left storage section 10 or the right storage section 20, so when the handbag is not used as a backpack, the shoulder strap 30 can be removed.
[0015] Numerous storage compartments are provided inside the left storage compartment 10 and the right storage compartment 20, allowing clothing to be stored according to its intended purpose. The bag can be folded with clothing stored inside and closed with the zipper 50 for compact storage, and can be carried like a carry bag using the handle 40 or carried like a backpack using the shoulder strap 30.
[0016] A review of the domestic and international technical information documents relating to the invention as described above clearly shows that there was no identical or similar structure prior to the invention. Therefore, the invention and its similar products are found to be inventive and practical. Therefore, the invention meets the requirements for registration under the Utility Model Act, namely, "creativity," "industrial applicability," and "inventive step."
[0017] The above description is merely a preferred embodiment of the present invention, and all uses of the present invention and equivalent structural modifications thereof are intended to be within the scope of the utility model claims of the present invention. [Explanation of symbols]
